TO ALL WHOM I'l MAY CONCERN:

Be itknown that I, FREDERICK W. HUPPELSIJE'RG, of No. 83 WestThirty-Seventh street, in the city, county, and State of New York, haveinvented a new and useful Improvement in Looms; and'I do hereby. declarethat the following is a full, clear, and exact description thereof,reference being had tothe accompanying drawing` in which.-- Y I Figure Iisan elevation in side view of a loom contaiisiingl improvement. Figure2 is a front elevation. Figure?) is a plan view. Figure 4 is a 'diagramwhich shows theshape of the cloth Woven 'on the loom, and alsothefmannerof placing or interweaving the weft in the warp'during theprocess ot` weaving. v

The object of this invention is to construct or produce a loom wh edgesshall describe concentriccircles, so that when the ends of a piece ofgoods woven on such loom are united the said piece forms a hollowtruncated cone, the projection ot` which resembles the diagram, lig. 4,said figure being a representation of a piece ofgoods produced or wovenby means of my invention.

My invention Kalso embraces features which are applicable to ordinarylooms. The frame of the loom is of any suitable construction or formto4sustain the various parts, and I have shown only such parts of a loomas are necessary, in order to show and illustratemy,improvement. l i Theletter D designates the lathe, whose swords are suspended from the upperpart of thefrarne.V shuttle-race E is attached te the lathe as' usual.Said-shuttlelrace is so made as to 'eX-tend a greater distance beyondone side of the frame of the loom than it doesbeyond `the other side,for the purpose hereinafter explained.l The warp-threads are guided andseparated, as sual,.by the reed in the lathe, and theyI are alsognidednnd separated as they enterthe loom by means of rods M, placedverticallyiritherear part of the frame of the loom.l VThe bobbin orspool-frame A, which holds the spoolsvof the warp, ,is arranged in ahorizontal position instead of a vertical or inclined position. .Saidspool-frame A is hinged to the frame of the loom or otherwise attachedto it, so that it may be swung upwards against the loom when it is notin use, and. when said' frame A. is in its horizontal position it issupported therein by legs B, one or more resting ori the'iloor. lTheframe A is composed of numerous parallel strips or ribs PP, which haveangular slots C C made across them at regular distances apartl toreceive the ends or journals of the-spools orbobbins containing thewarp, the ribs P being far enough apart to allow space hetween'them forthe bobbins. v I

. By means of this arrangement VI am enabled to make the spool orbobbinsframe apart ofjthe loom itself, and to dispose the `spools in ahorizontal position, and to dispense with the usual costly and cumbrousindependent bobbin-frame non' employed for holding the warp-spools. Thecloth woven upon the loom is taken up by meanslo a system of conicalrollers or surfaces.V -exampleof my invention I einploy two conicaltake-up rollers J andK, whose axes are so arranged that the upper sideoftheperiphery of the upper roller `J is level with the` cloth that isbeing woven,-` sequently inclined, as shown in the drawing. Tho'bearingsof said upper roller are xed,` but roller K are movab1e, being formed inthe inner ends else are provided with movable weights that cause thunder surface of the upper roller. The lower roller lreceives its motionfrom frictional contact With the upper roller J, and the latter isrotatedlby means of a. train of geared wheels, I I I-I, which. aro-made'to Yrotate by means of the vibration of the lathe through the' cords GG and levers F F',the latter lever I4" being weighted, "and beingprovided jwith a spring-paul that engages the teeth of a ratchet-wheelonthe lower gear H, on whose shaft thosaid lever F is placed, turningloosely thereon.V When the lever FQ is moved up'vvnrds by .the{fibration ofthe lathe inbeat'ingup,

on cord G is ich will automatically weave goods whose its'axis beingconthose of the lower of levers L L, the outer ends ot which aremadevheavy or relieved by the return 'or backward motion-,of .the lathe,theweight on said'lever F causes the "lever to fall so that thespring-pawlcan Vengage a fresh toothof said ratchet-wheel, the ratchetand gear lbeing Any other suitable .Take-up device means4 of ajncquardapparatus and N; but I have not shown the jacquard nor the leaves|`prevented from turning backwards-by means of a detent, Q, may beemployed insteadr of the one here shown. leaves of harness .inconnection with'a trap-board seen in iignl. vThe warp is operated byframek The A' e lower end to be pressed constantly upwards against thedthe spring-pnwl turns the gear H a proportionaldistance, and when the'sti-ain* Y novelty in th'm.
